A. K. Singh, “Solvent Effect on the Enthalpy and Entropy of Activation for the Hydrolysis of Ethyl Cinnamate in Mixed Solvent System,” International Journal of Engineering and Applied Computer Science, vol. 02, no. 04, pp. 123–126, Apr. 2017. http://dx.doi.org/10.24032/ijeacs/0204/01
Abstract—The rate of alkaline hydrolysis of ethyl cinnamate was measured over the temperature range of 20o C to 40 o C in water-acetone mixture at different composition 30 to 70% (v/v). The influence of solvent variation on reaction rate was examined in term of changes in the activation parameter. Depletion of H* and S* value with simultaneous increase in G* of the reaction in reaction media, reveals that the reaction is Enthalpy domination and Entropy controlled. The Iso- dielectric activation energy(ED) of reaction was found to decrease from 52.43 to 47.28 which is calculated by plotting log k values against different D. The Values of Iso-kinetic Temperature which is less than 300, clearly indicates that there is no appreciable interaction between solvent and solute present in the reaction media, i.e. reaction is not ion-dipole but ion-molecule type.

Kumaraswamy , “Experimental Characterization Strategies of NonLinearity Measurement Exhibitions for The Wideband LNA in IEEE L and S Bands,” International Journal of Engineering and Applied Computer Science, vol. 02, no. 04, pp. 127–132, Apr. 2017. http://dx.doi.org/10.24032/ijeacs/0204/02
Abstract— In this paper, the test portrayal strategies of nonlinear measurements of wideband LNA exhibitions are simulated. Likewise, significance of the nonlinear estimations has been portrayed unmistakably with microwave LNA operating large signal analysis had been assessed. This work is endeavored to demonstrate the performances of the LNA with AM-AM, AMPM measurements in points of interest and differentiating from the linear measurement regime. The most of the important aspects of LNA will be in linear measurements and furthermore to quantify nonlinear measurements accurately harmonic balance simulator is used. The harmonics up to order 3 and power characteristics are altogether shown with power swept variable. A simulation setup is made to measure the characteristics of LNA by using spectrum rectangular display type with power harmonic components. At last, author designed wideband LNA from the bandwidth 1 GHz to 5 GHz and elaborates how nonlinear measurements changed the way of LNA design to validate and development in microwave frequencies.

Abstract—In this paper, we use the clustering technique to monitor the status of students’ scholastic recital. This paper spotlights on upliftment the education system via K-means clustering. Clustering is the process of grouping the similar objects. Commonly in the academic, the performances of the students are grouped by their Graded Point (GP). We adopted Kmeans algorithm and implemented it on students’ mark data. This system is a promising index to screen the development of  students and categorize the students by their academic performance. From the categories, we train the students based on their GP. It was implemented in MATLAB and obtained the clusters of students exactly.

Abstract—In this communication era, wireless sensor network places a vital role. Wireless sensor network comprises of various types of sensor networks. Deployment of sensor nodes in wireless sensor network is a major concern to optimal result. There are various techniques in deploying the wireless sensor node. Among those some of the methods are, randomized method of deployment, grid based deployment, contour based deployment and projection based deployment. In this paper we are comparing all above methods and we show that projection based method out performs the rest of all othermethods.

Abstract—Energy is one of the main network resources that is used in mobile devices. We proposed an energy efficient routing techniques called reliable minimum energy cost routing (RMECR) and comparing with reliable minimum energy routing (RMER) which are used by the nodes in the most efficient manner. RMER and RMECR works on the basis of balancing the energy of the nodes so that the nodes with maximum energy can do the work and the nodes with less than certain threshold energy required to do a certain amount of work will not do any work. Thereby we try to raise the network reliability and lifetime of communication in a network of mobile devices. The proposed RMECR protocol is also used to decrease the cost of communication in a wireless networking environment.
